4TAPPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 654,481, dated July 24, 1900.

Application filed November 22, 1899. Serial No. 737,905. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, HENRY NADORFF, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Iinprovements in Tapping Devices, of which the following is a specification.

My invention relates to tapping devices, and contemplates the provision of a device through the medium of which a barrel of beer or other beverage may be expeditiously tapped and supplied with air or gas without loss and one which, as compared with devices at present in use, is extremely simple, cornpact, inexpensive, and durable and is susceptible of being readily repaired when necessary.

With the foregoing in mind the invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure l is a sectional view illustrating my improved device in its proper operative position with reference to the head of a barrel. Fig. 2 is a broken perspective view of the sleeve-section of the device. Fig. 3 is a diametrical section illustrating the bushing which forms part of my improved device and the bung therein. Fig. 4 is a view, partly in section and partly in elevation, illustrating the peculiar and advantageous ai r-nipple and non-return valve. Fig. 5 is a face viewof the bushing.

Referring by letter to the said drawings, A is the head of a beer or other barrel, which is provided with the usual bung-hole c, and B is a bushing forming part of my improved device. This bushing is exteriorly tapered and threaded to permit of it being screwed into the bung-hole and fixed in position and is preferably provided at its outer end with an exterior iiange b, designed to serve as a stop and limit its inward movement. It is also provided with an inwardly-tapered bore c, designed to receive a correspondingly-tapered bung C, of cork or other suitable material, and at its outer end has an inwardlydirected flange d. The said flanged is provided in its inner edge and at diametricallyopposite `points with grooves c and is also pro vided at its inner side with two oppositelyto pass through the' grooves e of bushing B and are beveled, as shown', whereby it will be seen that when the'sleeve-section is placed in the position shown in Fig. l and given a partial turn it will be drawn inwardly with respect to the barrel. yThen this is done, a gasket E, otl rubber or other suitable mateh, willbe pressed against the face of the bushingB and an air-tight connection between the sleeve-section and said bushing will be effected. It will also be seen that when the rubber gasketis compressed, as stated, it will, by tending to expand, hold the lugs g securely against the inclinedv planes f, and thereby eifectually prevent casual disconnection of the sleeve-section from the bushing.

In addition to thelugs g and flange h the sleeve-section D is provided with a lateral arm t', interiorly threaded at its outer end. Said sleeve-section is also provided with a chamber j in communication with a chamber 7e in arm and at its outer end has a bore Z, comparatively small in diameter. This bore lis designed to snugly receive an endwisemovable draft-tube F, which is equipped at its outer end with the usual cock G.

An air-tight connection is eected between the tube F and sleeve-section D through the medium of a gland H, screwed on the outer end of the latter, and a packing-ring I, contained in said gland.

.I is the air-nipple of the device, which is designed for the connection of theusual air or gas supply tube. This nipple is threaded at m to engage the interior threads of the arm t' and is provided with the usual flange n, between which and the end of the arm 'L' a gasket 19 is interposed, as shown. Said nipple is also provided with an inner reduced portion q, which is tapered toward its end, as shown, and is provided with a diametrical port r in communication with the bore of the nipple.

K is a sleeve of rubber which snugly surrial, arranged at theinner side of the flange -rounds the end portion q of the nipple and ewzrtends beyond the same, as best shown in When air is forced in the direction of the arrow in Fig. l, it will pass from the bore of the nipple J through port r and pressing the rubber sleeve4 away from the portion q of the nipple will pass into the chamber 7c of the sleeve-section and from thence through the chamber j and bushing B into the barrel. Such air is, however, effectually prevented from rentering the nipple and passing out of the barrel by virtue of the fact that the pressure in the chamber 7s presses and holds the sleeve K against the portion q of the nipple.'

It will be appreciated from the foregoing that the sleeve K forms a highly-efficient nonreturn yvalve and is not liable to be connectedto and secured in a closed position on the nipple portion q by the adhesive ingredients in the beer. This latter is due in large measure to the taper of the nipple portion and the extension of the sleeve beyond the end of the nipple portion, which extension is held open by the nipple portion and is occupied by the air or gas present in chamber 7c, which tends to prevent the sleeve being set by the adhesive in the beer against the nipple portion and is assisted in such action by the taper of the nipple portion. The taper of the nipple portion and the extension of the sleeve beyond the end of the nipple porl tion are also advantageous, since they permit of the sleeve being readily drawn o the nipple portion when it is desired to replace said sleeve with a new sleeve.

In using my improved device to tap abarrel of beer and supply the same with Aair or gas the sleeve-section D is connected to the bung-bushing B in the manner before described, and the nipple J is connected with a source of air or gas supply. The tube F is now-moved down until its inner end bears against the bung C and is struck by a mallet and driven inwardly until the bung C is forced out of the bushing and into the barrel. This operation is of course carried out while the cock G is closed; but after the tap is effected and the beer-pipe connected to the cock G said cock is opened.

It will be seen from the foregoing that myV improved device is so constructed that the beer or other liquid is effectually prevented from deteriorating any ofV its parts; also, that the rubber sleeve K, which is the only said reduced or tapered portion q of the nipple and extending beyond the inner end thereof, as and for the purpose set forth.

2. In the tapping device described, the combination ofthe bushing ixed in the bung-hole of a barrel and having the taper bore c in its inner portion adapted to hold a bung of cork or other suitable material, and also having the inwardly-directed flange at its outer end, provided in its inner edge with opposite grooves, and also provided at its inner side with oppositely-disposed inclined planes, the sleeve-section having lugs at its inner end adapted to pass through the grooves and engage the inclined planes of the bushingiiange, and also having the integral exterior Iiange h adjacent to its inner end, the eXterior'threads at its outer end, the bore Zin said outer end, the chamberj and the arm 1l cornmunicating with said chamber, a removable nipple screwed into the end of said arm t' and having the inner reduced and tapered portion q provided with a diametrical port communi-v cating with its bore, the removable sleeve K of rubber arranged on said reduced or tapered portion q of the nipple and extending beyond the inner end thereof, the gasket surrounding the sleeve-section below the flange h thereof, the gland mounted on the outer threaded end of the sleeve-section and con-v taining packing and the endwisemovable ldraft-tube extending through the sleeve-section and the gland thereon, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY NADORFF.
